"The Old Man feeds us well," Beresford remarked, handling his chopsticks dexterously. "He doesn't want to hasten Nature's destructive work by starving us. Drinking-water, by the way, is got from a little stream that trickles into the lake just round the corner. I confess I shouldn't care to drink the water in which that antediluvian monster disports himself. We'll take a look at him presently--if we get a chance, for he appears to be rather shy: I suppose he feels hopelessly old-fashioned, or perhaps he has an aristocratic pride in his long descent, and scorns the company of such new creatures as mere men."

"Why isn't the place more stuffy than it is?" Forrester asked. "Where does the air come from?"

"That puzzled me at first, but I discovered the other day that there is a constant current of air, slight, but quite perceptible, over the surface of the lake, through this cavern, and into a narrow cleft which I'll show you by and by. There must be a passage into the upper air. The temperature is rather too high to suit me; but the air is pure enough, and many of the dungeons in medieval castles were much worse places--barring the peculiarly oppressive effect of the stuff below.... You don't get on very well with your chopsticks. Like everything else, they require practice."

"One thing I can't make out is why we are allowed such freedom. You seem to be at liberty to move about as you please, talk to the prisoners--you speak Chinese?"

"Yes, but only out of earshot of the priest in his sentry-box yonder. I don't want him to blab to the August and Venerable--not that it matters, perhaps. The explanation of our freedom is, of course, that it is only such freedom as birds have in a cage. The passage by which we came is barred by the guards. There are no tools or implements of any kind which could be used as weapons; in fact, there's nothing here but ourselves and a few bamboo rods yonder against the wall, which I fancy must be used for keeping the sentry-box in repair. It's rather dull work for the priest, sitting there all day alone and mum; a new fellow comes every day."

After dinner Beresford led Forrester back to the transmuting cavern, and across it into a passage similar to that by which they had reached the spot. It was a cul-de-sac, except that at its further end there was a narrow cleft in the wall. The opening was barely a foot wide, and the sides were of solid rock. There were slight marks which seemed to indicate that at some time or other an attempt had been made to enlarge the opening by chipping; but the marks were very old, and it was clear that the task, if attempted, had been abandoned as hopeless. The cleft had a slight upward slope, but looking along it, Forrester saw no sign of daylight, nor did he hear any sound from the further end, which was not visible. They both agreed that no human being could possibly squeeze himself through so constricted a passage.

Returning to the outer cavern, they went to the entrance and stepped on to the ledge outside. They peered across the gloomy lake, but failed to discover the monster whose image they had seen outlined on the wall.

"He is not at home to-day, evidently," said Beresford. "Well, we have exhausted the objects of interest: all that we can do for the rest of the day is to sit on our bunkers and 'tell sad stories of the death of kings' or anything else you like. Later on I'll tackle the prisoners again. I try to stir them up a bit and get them to talk, without much success so far except with Wing Wu and his cousin. They are so horribly depressed, poor wretches! By Jove! I do wish I had my pipe."

It was impossible to gauge the passage of time. The successive days, as Beresford explained, were marked only by the arrival and departure of the guardian priests, and by the cessation from work of the man in the smaller cavern, who returned to his companions when a certain number of the leaden plates had been changed into gold. These were placed in charge of the priest on duty, who superintended their removal by the negritos when relieved next day.

That night, Beresford found the two younger Chinamen a little more communicative than they had been before. Wing Wu, indeed, evinced much pleasure in meeting Forrester again, and talked to him with a certain eagerness in English. He was the eldest son of a mandarin, he explained, and had kept a few terms at Oxford. Wen Shih, who had passed with distinction the innumerable examinations inflicted on Chinese literati, had been for a few months his father's secretary. In some subtle fashion he had obtained a commanding influence over the young man. Always courteous and agreeable, he enjoyed the complete confidence of his master, and gradually Wing Wu found himself consulting the secretary in every circumstance of his life, however trivial, until he lost all independence of judgment and even of action. He was at Wen Shih's beck and call, did his behests even against his own will, and felt that Wen Shih dictated the words he uttered, and arranged his very thoughts.
